Abstract

Abstract In a wrist watch equipped with a receiving device, an antenna 19 having an antenna winding 19b, wound around an antenna core 19a with the end thereof being fixed, and having a conductible antenna terminal sheet 19d secured to an antenna winding frame 19c is inserted from a notch 10k in a dial 10 and secured with a screw 35 to an antenna support plate 33 which is secured to a circuit substrate 22, there by conducting the antenna 19 and the watch module. The construction ensures simplification of the watch module structure and easy conduction and securing of the antenna and the watch module and secured, with little influence on the receiving performance.

Claim 3
Dependent Claim 76 words
The electronic wrist watch equipped with a receiving device according to Claim 1, wherein said antenna has an antenna wire, wound around an antenna core with the end thereof being fixed and having a conductible antenna terminal sheet on the both ends, said antenna terminal sheet being inserted into a timepiece module from above the timepiece display section and said antenna being conducted and secured on an antenna support plate of the timepiece module with screws.
Claim 4
Dependent Claim 34 words
The electronic wrist watch equipped with a receiving device according to Claim 1, wherein a shield plate is provided between said antenna and the circuit substrate and between said antenna and a step motor.
Claim 5
Dependent Claim 31 words
The electronic wrist watch equipped with a receiving device according to Claim 1, wherein said antenna is provided over the timepiece display section at a place higher than the watch case.
Claim 6
Dependent Claim 33 words
The electronic wrist watch equipped with a receiving device according to Claim 5, wherein a bezel secured to the watch case and provided on the periphery of the antenna is made of ceramic.
Claim 7
Dependent Claim 30 words
The electronic wrist watch equipped with a receiving device according to Claim 5, wherein an indented section is provided on the undersurface of the glass windshield for housing the antenna.
Claim 8
Dependent Claim 45 words
The electronic wrist watch equipped with a receiving device according to Claim 5, wherein the antenna is positioned on the longitudinal direction passing through the center of the dial so as to make the display areas on the both sides of the antenna almost equivalent.
Claim 9
Dependent Claim 41 words
The electronic wrist watch equipped with a receiving device according to Claim 8, wherein the dial is provided on the right side of the timepiece display section and a function display section is provided on the left side of the dial.
Claim 10
Dependent Claim 41 words
The electronic wrist watch equipped with a receiving device according to Claim 9, wherein said function display section for displaying functions other than the time, which is provided on the left side of the antenna in the dial, is sectorially formed.
Claim 11
Dependent Claim 38 words
The electronic wrist watch equipped with a receiving device according to Claim 9, wherein the hand provided on the dial in the left side of the antenna for displaying functions other than the time performs a monitor display.
Claim 12
Dependent Claim 26 words
The electronic wrist watch equipped with a receiving device according to Claim 1, which has a mode displaying section wherein the time is switched by hands.
Claim 13
Dependent Claim 204 words
The electronic wrist watch equipped with a receiving device according to Claim 12, which comprises, a mode wheel on which is mounted a mode hand which indicates various functions; an intermediate mode wheel with a gear section for engaging the mode wheel and a plurality of angled sections; a setting lever for engaging an external operating means; a setting lever spring which engages the setting lever and determines the positioning of the setting lever; a rotatable mode switching lever engaging the setting lever; a return spring for engaging the mode switching lever and imparting spring pressure in the direction of the setting lever; a jumper for engaging the angled sections of the intermediate mode wheel and positioning the rotating direction of the intermediate mode wheel; and a mode switching spring which rotates with the intermediate mode wheel and bends between the intermediate mode wheel and a circuit substrate; and wherein the mode switching lever is pressed by the setting lever by operating an external push-pull operating member, effecting the contact of the tip of the mode switching lever and an angled section of the intermediate mode wheel and rotating the angled section for one pitch rotation, thereby rotating the mode wheel for one mode.
Claim 14
Dependent Claim 85 words
The electronic wrist watch equipped with a receiving device according to Claim 13, wherein said intermediate mode wheel has a plurality of angled sections for appropriately matching the stroke of the mode-switching lever driven by the operation of the external operating member and the stroke of one pitch part of the angled sections of the intermediate mode wheel, thereby performing the conduction between mode-switching patterns corresponding to each mode by means of a mode-switching lever switch spring which rotates together with the intermediate mode wheel.
Claim 15
Dependent Claim 156 words
The electronic wrist watch equipped with a receiving device according to Claim 1, which has a sector receiving device according to Claim 1, which has a sector display gear train modification mechanism comprising, a hands wheel for sector display by hands from the rotation of a step motor forward and in reverse; a rotor for driving the hands wheel; a slowdown gear train for transmitting the rotation of the rotor to the hands wheel, a regulated member being formed on the slowdown gear train between the hands wheel and the rotor and a rotation regulating member linked to an external operating member being further provided; and wherein said rotation regulating member engages a controled member in the foward rotation direction of said rotor and rotates to the direction apart from said controled member, whereby it is possible, by means of the rotation regulating member, to extricate said rotor from a condition in which reversing is impossible.
